I'm on the market for a new monitor. Mine is a very old Asus that is a 1080p/60hz monitor.

A few days ago I used to be the occasional competitive player (just playing with friends) and while I might play a competitive game or two again, I'm wondering if I should buy the BenQ Zowie 2546K. Where I'm looking (local market), it's currently the lowest price it's ever been.

But my hesitation lies on the fact that I might have more use for a 4k/140hz monitor.

I guess I'm mostly looking for personal recommendations.
